3.2.5 RFID Sensor
Figure 49: RFID sensor.
This sensor is useful for synchronous recording of biosignal data and ID-mappable events.
Usage examples include token detection and reaction time analysis in object
manipulation tasks, and also differentiated event annotation.
How to connect your sensor to your biosignalsplux
The RFID sensor can be connected to any of the available analog inputs of your
biosignalsplux device (see 2.3.2 Analog Inputs).
This sensor does not require an additional reference electrode.
How to configure your sensor in OpenSignals (r)evolution
Open the OpenSignals (r)evolution device manager and select the device you have your
RFID sensor connected to. Select the channel of your RFID sensor and select CUSTOM
from the dropdown menu (click on the arrow in the channel’s field that appears when you
hover over the channel’s field). In the custom field of your channel, adjust the GAIN and
OFFSET that fits best to your application. Testing and readjustments of this parameters
might be needed to find the configuration that fits best your needs.
Alternatively, you can also use the RAW option, which will display the raw digital signals
that are received from the biosignalsplux.
Activate this channel for signal acquisition by clicking on the circle in the channel field
(must be blue).
An example configuration is displayed in Figure 50 (here: RFID sensor connected to
channel 1).
